Question

How is Atomic Fluorescence Spectroscopy described in the document?
Options
A It measures the intensity of light emitted by excited atoms returning to ground state.
B It quantifies the absorption of ground-state atoms in the gaseous state.
C It involves atoms absorbing radiation and then re-emitting it as fluorescence, combining aspects of absorption and emission.
Correct Answer
D It studies the electromagnetic radiation emitted or absorbed by atoms.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 7 states: "Atomic fluorescence spectroscopy: Atoms absorb radiation and re-emit it (fluorescence). This is a combination of atomic emission and atomic absorption as it involves radiation of both excitation and de-excitation."

Hint

The name itself gives a clue about the process, combining absorption and re-emission.
